View Full Version : Using Stored Procedures


03-26-2008, 12:23 PM
I looked in the What's new in V9 and have not found any information on how to execute a stored procedure within a firebird sql database or any other.

Is there any available info on this ?

I've been running stored procedures against Firebird with version 8. Here's one that I generalized a bit for this example. The fldlist and valuelist variables are, of course, created before this:

dim conn as ole::adodb.connection
dim rs as ole::adodb.recordset
rs.CursorType = 3
sql = "INSERT INTO USERS (" + fldlist + ") VALUES (" + valuelist + ")"
Success_Flag = rs.open(sql, conn)

Also, v8 had (and I am pretty sure v9 does too) a genie that would call a stored procedure. But note that for mysql one had to manually put "call" in front of the name of the stored procedure. The "call" is probably only necessary for mysql.

On second thought, I suppose I should have been a bit more specific. I meant there is in V8 an xabasic script genie (same thing for action scripting) under SQL (using AlphaDAO).

Edit: I was going to put a screen capture in here but I guess I am too ignorant (or lazy) to figure out how to do that. Sorry.

Thanks to you guys, I was able to find the unique code to run a stored procedure in firebird: EXECUTE PROCEDURE and have a local ask variable passed into the procedure to query on the correct information.

However, in using an ask variable, I am having the dialog box pop up twice....The first time it pops up and I enter in data, it seems to rerun its self with the default entry reset to its initialized value.

The section in blue is the troubled section. It can be tested independently of the remained of code. Anyone know why it would do this ?

Try setting a variable to = ui_get_number(prmpt_title,prmpt_prompt,prmpt_default)
farther up in your script and then plug the variable into your arg.add() line.

I should have clarified, but I did that already and then it works fine. I guess I am curious why it repeats when I merge the ask within the sql arg definition..........
